Building Out XenServer 6.5 with USB Boot and Software RAID 10

Alex Sage

@DustinB3403 Ah, I see. Have you tried a fresh install?

DustinB3403

@aaronstuder Working on that now.

DustinB3403

It looks as though I'm going to have to clean the drives that are a part of the old array before I can proceed. I'm getting an error

 no such file or directory: '/sys/block/md127p1'

Alex Sage

@DustinB3403 Bummer. On a side note, how do I quickly remove all partitions on a drive in Linux? I want a blank drive with nothing on it

I'm assuming on the software array, correct?

mdadm --stop /dev/md0
mdadm --remove /dev/md0
mdadm --zero-superblock /dev/sda    (per drive)
sfdisk -d /dev/sda | sfdisk /dev/sdb

@aaronstuder

parted /dev/device
rm 1

Repeat rm for each partition on the drive.

Edit: @DustinB3403 method is better if it's an mdadm array.

@travisdh1 @DustinB3403 Thanks guys!

I had to erase each of the disks before being able to proceed.

So if this were a production system or other system that you really want your VM's from take a backup.

DustinB3403

I've selected no VM storage, and enabled Thin Provisioning at the initial screen. I'm checking the installation media for issues as well. I'll update shortly from there.

So far no issues found.

Proceeding.

That means you cannot upgrade.

DustinB3403

@JaredBusch Correct.

With this system I had removed the bootable USB prior too, with it in place I may have been able to upgrade.

But since this was a test system it was already torn down and the drives had data stuck to them that was causing some issues.

DustinB3403

So I was able to upgrade, obviously the array is gone.

With XS7 you need to install a newer version of XenCenter if you want to manage it.

@DustinB3403 The new version is backwards compatible with 6.5 though.

Good to know, I was just about to test.
